Configuration procedure
1. Assign an IP address and subnet mask to each interface according to Figure 43. (Details not
shown.)
2. Configure OSPF on the routers in the PIM-DM domain to make sure the following conditions are
met: (Details not shown.)
{ The routers are interoperable at the network layer.
{ The routers can dynamically update their routing information.
3. Enable IP multicast routing, IGMP, and PIM-DM:
# On Router A, enable IP multicast routing.
<RouterA> system-view
[RouterA] multicast routing
